Issue:
======
SQL Server 7.0 and 2000 provide stored procedures which is a coll-
ection of Transact-SQL statements stored under a name and processed
as a group. One stored procedure, an extended stored procedure and
weak permissions on a table combine to allow a low privileged user
the ability to run, delete, insert or update web tasks.

An attacker who is able to authenticate to a SQL server could delete,
insert or update all the web tasks created by other users. In
addition, the attacker could run already created web tasks in the
context of the creator of the web task. This typically runs in the
context of the SQL Server Agent service account.

Mitigating Factors:
====================
- - It is necessary to be an authenticated user of the SQL Server.
- - Exploiting this vulnerability could allow the attacker to escalate
privileges to the level of the SQL Server service account. By
default, the service runs with the privileges of a domain user,
rather than with system privileges.
- - Web tasks have to exist in the first place.
